Analyze how color can be used to create moods and illusions. Explain how primary colors are used to produce other colors on the color wheel. Describe the effects of intensity and value on various hues. Eric King. Humans perceive color when light enters the eye and is detected by the photoreceptors, called cones, which are mainly located in the fovea. We have trichromatic color vision which means we have three different kinds of cones that detect a specific wavelength of light, namely short (blue), medium (green), and long (red). How we perceive color also depends on how dim or bright the light is. . http://commons.wikimedia.org/wiki/File:Eye-diagram_bg.svg . Light. Light. Particles known as photons. Act as ‘waves’.
